Band 9: The diagram below describes the structure of a home smokery and how it works. Summarise the information by selecting and reporting the main features and make comparisons where relevant.

The provided diagram illustrates the layout and process involved in food smoking.

The smokehouse comprises three primary components: an air inlet, a firebox for smoke generation, and a chamber that contains the food and is exposed to the smoke. The system’s operation commences with air intake and culminates in the smoking of the food.

In the initial phase, air enters the system through a small vent or air inlet situated underground. This incoming air flows into the firebox, where logs are placed to produce smoke. As the combustion process generates smoke, it travels through a connecting pipe from the firebox.

In the final phase, the smoke enters the chamber, which is situated above ground and constructed of bricks. The food is suspended from the upper portion of the chamber, facilitating efficient smoke circulation and cooking. The structure and design of the smokehouse enable the smoking of food, a domestic preservation technique.
